How do get around stripped binding posts? (Yamaha DSP-E492)

[Denis29]

A couple of binding posts (speaker outs) on my Yamaha DSP-E492 got stripped threads and do not tighten. The threaded studs are fine, but it's the threaded hole they go in that seems to not be able to grip 'em.

What are my options? I don't believe I can just take the binding post assembly out because it seems customized to this unit and soldered to the board... What's an easier solution?

Locking banana plugs?

Not exactly - that won't fix the problem for me. I have binding posts just like in the picture there... You know how you screw them down, so they clamp down on your wire - well the thread is stripped, so they don't exactly clamp down.

In my case, it's not the plastic that's threaded, like in speaker binding posts, but the stud under the visible part that screws into a hole. That hole has a stripped thread, so the binding post is loose.

Usually, the binding post has a nut on the inside that can be tightened. They put something on hte nut to lock the threads but when it's twisted, it breaks free. Look inside the receiver and make sure the nut is tight. If not, re-tighten it and if you have LocTite, use that. If you have model paint, nail polish or something like those, it'll work just as well.

I ended up finding a 2 small nuts that fit the binding post stud and threading them onto the two studs that were stripped from inside the box. While not the most elegant solution, the binding posts are now firmly in place. This will restrict me to using banana plugs, but that's the best, quickest, and cheapest solution here, I think.

Yea, I see what you're saying, but these binding posts don't have a nut on the inside... Just a threaded hole. This would be fine, except Yamaha used such fine thread (which doesn't have much depth to it) and such a small stud that it is only a matter of time before the holes get stripped of their threads from overtightening or frequent use. Stud threads were fine.

Anyhow, as I said above, I secured the studs that were stripped with nuts. I didn't put any locking compound on... If I need to do that in the future, it shouldn't be hard.

Thanks!
